Just set your refresh rate to 75Hz in Windows. Games also have their own refresh rate settings which might not be accessible in some games and always runs at 60Hz. Refresh rate also depends on the resolution. At native resolution its rare to find an LCD with more than 60Hz. At lower resolutions you can usually increase the refresh rates.

There is generally no visual difference between running at 60Hz and above except for very fast moving scenes. There are some games like CS 1.6 though where the engine is internally tied to the FPS making it impossible to aim right if it isn't running at 100FPS. If you want VSync, the mouse lag can be mitigated by increasing the number of prerendered frames in the the graphics control panel.
